SPECIFICATION forming part of Letters Patent No. 479,903, dated August2, 1892.

Application filed December 14, 1891.

To all whom it may concern:

Be it known that we, LOUIS TEWELES and THOMAS A. ROBINSON, citizens ofthe United States, residing in Paterson, county of Passaic, and State ofNew Jersey, have invented certain new and useful Improvements in Pickersfor Looms; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters andfigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to improvements in novel features hereinafterdescribed and claimed.

In the annexed drawings, Figure 1 is a front elevation of a loomprovided with our improved picker, only such parts of the loom beingshown as are necessary to properly illustrate the operation of thepicker. Fig. 2 is a plan view, on a larger scale, of a portion of theraceway, showing the picker in its proper position relative thereto.Fig. 3 is an enlarged sectional view on the line so of Fig. 1, and Fig.4 is an enlarged detail view of the picker.

In the drawings, A represents the loomframe, on which the raceway Boscillates in the usual manner, a fly-shuttle 2 being thrown over saidraceway by picker-sticks a a. To the back of the raceway is secured anupwardly-extending frame C, provided with an upper raceway D, parallelwith the raceway B and a suitable distance above the same. This frame Gis also provided with openings H D", in which are inserted reeds B Darranged at opposite sides of the center of the loom, as clearly shownin Fig. 1.

Theraceways B D are provided with registering longitudinal slots b d,which guide the pickers a and the picker-sticks a, as clearly shown, andon each side of the reeds B D the raceways are provided with theshuttle-boxes c c and ff. The said shuttle-boxes are of differentlengths and are so arranged as to almost equal the distance from theoutside ends of their respective slots to the inside ends of Serial No.414,944. (No model.)

their respective reeds, as clearly shown in Fig. 1.

The picker a, is secured to the picker-stick a by a leather strip andconsists of the upright arm a provided at one end with an enlargement apartially or wholly surrounded by a leather pad a and at the other endwith an enlargement a to which is secured ahorizon tally-extending arm aof a length equal to the length of its respective shuttle-box, less thelength of a shuttle. The free end of this arm is provided with across-head a adapted to slide on the surface of its respective raceway,and is also wholly or partially surrounded with a leather pad a Theupright arm a? is adapted to slide in the elongated slot d and its lowerenlargement to travel on the surface of raceway B.

In Fig. 4 of the drawings we have shown a detail view of the pickercorresponding with the right-hand side of Fig. 1. The arrange- 7o mentof the picker for the left-hand side of the loom is similar; but thehorizontal arm is attached to the lower enlargement of the upright arm aand the upper enlargement is provided with a leather pad.

The shuttle-boxes are provided with binders it, connected with theloom-stopping mechanism in the usual manner, and the warp and take-uprollers are made in sections M M and N N.

' In operation the lower and upper shuttles are thrown across theloomsimultaneously by the picker-sticks and their pickers, and there by twoindependent pieces of fabric may be woven.

Our improved picker is very simple in its construction and will operaterapidly without any tendency to bind on the raceways.

Having thus described our invention, what we claim, and desire to secureby-Letters Patcut, is'- 1. The combination of a frame having an elevatedraceway and adapted to be secured to the raceway of a loom paralleltherewith, shuttle-boxes arranged on each of the raceways, shuttlesoperated from said boxes, a vertical arm having enlargements at its endsand connected to the picker-stick by a flexible strip, said arm restingon the raceway of the loom and extending up through the upper raceways,a pad on one end of the said arm,

a horizontal arm secured to the other end of 5 the same, a cross-head atthe end of said horizontal arm, and a pad secured to the end of thehorizontal arm and around the cross-head.

2. A picker for looms, consisting of a vertical arm having an extensionat its lower end 10 adapted to ride on the lower raceway, a flexibleloop adapted to connect said vertical arm with the picker-stick, and ahorizontal arm connected to the upper end of said vertical arm andextending along the upper raceway.

In testimony that we claim the foregoing 15 we have hereunto set ourhands this 4th day of December, 1891.
